What the current evidence supports

Human editorial judgment · 2026-08-20

Track; not yet

Why
Furthest-along eVTOL with a real FAA-conforming aircraft flying and Stage 4 cleared, but commercial service is still gated on TC + air-carrier cert and unproven unit economics, with analysts expecting 2027
Next
Watch for FAA 'for-credit' TIA completion, Type Certificate issuance, and first Air Carrier Certificate / paid passenger flight before treating as operationally real
